Dear customer,
Our quality maxim is the ”zero fault principle”: Every rotary vane pump, before leaving our factory, is tested intensively, including an endurance run of 60 hours. Any faults, even those which oc-
cur rarely, are identied and can be eliminated immediately.
After completion of the endurance run, every pump is tested, and must
achieve specications before shipment.
We are committed to providing our customers only pumps that meet this high quality standard. While our pumps cannot eliminate all of your work, we design, manufac­ture and test them to ensure that they will be an effective and trouble-free tool to assist you in that work.
Yours, VACUUBRAND GMBH + CO KG

General information

NOTICE
Remove all packing material from the packing box. Re­move the product from its packing-box and retain all pack­aging until the equipment is inspected and tested. Re­move the protective caps from the inlet and outlet ports and retain for future use. Inspect the equipment promptly and carefully. If the equipment is damaged, notify the supplier and the carrier in writing within three days. Retain all packing ma­terial for inspection. State the item number of the product together with the order number and the supplier’s invoice number. Failure to check and give notice of damage will
void any and all warranty claims for those deciencies.
Replace the protective caps, if the equipment is not used immediately. Store the equipment in dry and non-corrosive conditions (see also “Technical data”, pg. 17).
+ Do not use any damaged equipment.
• Check the pump‘s oil level.
• If the pump is delivered without oil lling, ll in oil, see
section “Oil change”, pg. 32.
• Aging of the oil (as indicated by darker color compared
to new oil, strange odor of the oil, particles in the oil, or contamination) necessitates an oil change.
• Use the handle when moving the pump.

Intended use

+ Do not use the pump or any system parts on humans
or animals.
+ Ensure that the individual components are only con-
nected, combined and operated according to their de­sign and as indicated in the instructions for use. Use only original manufacturer’s spare parts and ac- cessories. Otherwise the safety and performance of
page 7 of 49
the equipment, as well as the electromagnetic compat­ibility of the equipment might be reduced.
The CE mark or the cTÜVus mark may be voided if not
using original manufacturer’s spare parts.
+ Comply with all notes on correct vacuum and electri-
cal connections; see section “Use and operation”, pg.
26.
+ Do not use the pump to generate pressure.
+ The pumps are designed for ambient temperatures
during operation between +54°F and +104°F (+12°C and +40°C). Periodically check maximum tempera­tures if installing the pump in a cabinet or a housing.
NOTICE
Make sure ventilation is adequate to maintain recom­mended operating temperature. Install an external au­tomatic ventilation system if necessary. If pumping hot process gases, make sure that the maximum permitted gas inlet temperature is not exceeded. The maximum permitted gas inlet temperature depends on several parameters like inlet pressure and ambient tempera­ture (see “Technical data”, pg. 17).
+ Particles and dust must not enter the pump. + Do not pump liquids.
• Ensure that the pump is chemically resistant to the
pumped substances prior to operation.
Use the equipment only as intended, that is, for genera­tion of vacuum in vessels designed for that purpose. Any other use will automatically invalidate all warranty and li­ability claims. Remain aware of safety and risks.

Setting up and installing the equipment

Equipment must be connected only to a suitable elec-
trical supply and a suitable ground point. As such,
the plug must be plugged into an outlet that is properly
page 8 of 49
grounded. Failure to connect the motor to ground may result in deadly electrical shock.
The supply cable may be tted with a molded Europe-
an IEC plug or a plug suitable for your local electrical supply. The cable contains wires color coded as fol­lows: green or green and yellow: ground; blue or white: neutral; brown or black: hot.
+ Due to the high compression ratio, the pump may gen-
erate overpressure at the outlet. Check pressure com­patibility with system components (e.g., exhaust pipe­line or exhaust valve) at the outlet.
+ Do not permit any uncontrolled pressurizing. Make
sure that the exhaust tubing cannot become blocked. If there is an exhaust isolation valve, make sure that you cannot operate the equipment with the valve closed to avoid a risk of bursting!
+ Keep the electrical power cord away from heated sur-
faces.
• Provide a rm, level platform for the equipment. Check
that the system which you are going to evacuate is
mechanically stable. Check that all ttings are secure.
Ensure a stable position of the pump without any me­chanical contact other than the pump feet.
• Comply with maximum permissible pressures at in- let and outlet and with maximum permissible pres- sure differences between inlet and outlet. See section “Technical data”, pg. 17. Do not operate the pump with overpressure at the inlet.
• Avoid overpressure of more than 17.5 psi absolute (1.2
bar absolute) in the event that inert gas is connected to the pump, to the gas ballast or to a venting valve.
Note: Flexible elements will shrink when evacuated.
• Connect hoses gas tight at inlet and outlet of the pump.
• Ensure that no foreign objects can be drawn into the
pump.
page 9 of 49
• Check the power source and the pump’s rating plate
to be sure that the power source and the equipment match in voltage, phase, and frequency.
Pump with dual-voltage motor: Check that the volt- age selection switch is positioned correctly. Check ev­ery time before starting the pump.
Note: If the pump is switched on with wrong voltage
selection, the motor may be damaged!
Change the selection at the voltage selection
switch only, if the pump is unplugged from the power source.
Direction of rotation of pumps with three-phase mo- tors: Pumps with three-phase motors wired ready for connection are supplied with a power plug (CEE). The electrical wiring is laid out for a right-handed rotary
eld.
Checking the direction of rotation: Switch on pump for a few seconds and check if the
pump aspirates at inlet. If no suction occurs switch off pump immediately. The three phase socket has to be checked and if necessary corrected by an electrician.
Use only oil of the recommended type. Other oils or operating uids may cause damage of the pump or
danger.
Use special oils (see “Oil change”, pg. 32) for the for the rotary vane pump, if, e.g.,
- acid vapors are pumped.
- extremely high aging stability is required.
- oxygen or other strong oxidizing agents are pumped.
• Take adequate precautions when handling pump u­ids, lubricants, and solvents. Use appropriate protec­tive clothing, safety goggles and protective gloves to avoid excessive contact with the skin and possible skin irritations (including dermatitis).
• Comply with all relevant statutory requirements and
regulations concerning the handling, storage and dis­posal of oil.
page 10 of 49
NOTICE
Make sure ventilation is adequate to maintain recommend­ed operating temperature. Keep a minimum distance of 2 in (5 cm) between the cooling fan and surrounding items (e.g., housing, walls, etc.), or else install an external auto­matic ventilation system. Check fan regularly for dust/dirt. Clean fan guard grill if necessary to avoid a reduction of ventilation.
Use only hoses at the inlet and outlet of the pump with an inner diameter at least as large as the diameter of the pump’s connections (to avoid overpressure at the outlet, and reduction of pumping speed at the inlet).
Allow the equipment to equilibrate to ambient temperature if you bring it from cold environment into a room prior to operation. Notice if there is water condensation on cold surfaces.
Comply with all applicable and relevant safety require-
ments (regulations and guidelines). Implement the re­quired actions and adopt suitable safety measures.

Ambient conditions

Do not reach for this product if it has fallen into liquid.
There is a risk of deadly electrical shock. Unplug the system immediately.
+ Do not use this product in an area where it can fall or
be pulled into water or other liquids.
• Adopt suitable measures in case of differences from
recommended conditions, e.g., using the equipment outdoors, installation in higher altitudes, conductive pollution or external condensation on the pump.
• Do not operate this product near ames.
page 11 of 49
NOTICE
To the best of our knowledge the equipment is in com­pliance with the requirements of the applicable EC-direc­tives and harmonized standards (see ”Declaration of Con­formity”) with regard to design, type and model. Directive EN 61010-1 gives in detail the conditions under which the equipment can be operated safely (see also IP degree of protection, “Technical data”, pg. 17).

Operating conditions

These pumps are not approved for operation in po-
tentially explosive atmospheres. Do not operate the
pumps in potentially explosive atmospheres.
These pumps are not approved for the pumping of po-
tentially explosive atmospheres. Do not pump poten-
tially explosive atmospheres.
The pumps are not suitable to pump any of the sub-
stances listed below.
Do not pump:
- unstable substances
- substances which react explosively under impact (mechanical stress) without air
- substances which react explosively when being ex­posed to elevated temperatures without air,
- self inammable substances,
- substances which are inammable without air
- explosive substances.
The pumps are not approved for operation below
ground. Do not operate the pump below ground.
Do not pump substances which may form depos- its inside the pump. The pumps are not suitable for
pumping substances which may form deposits inside the pump. Deposits and condensate in the pump may lead to increased temperatures even to the point of exceeding the maximum permitted temperatures. De­posits may cause seizing of the pump unit.
page 12 of 49
• Check the inlet and outlet of the pump and its oil condi­tion, if there is a danger of forming deposits inside the pump, e.g., in the pump unit. Inspect the pump regu­larly and clean if necessary.
• Install a cold trap in front of the pump if pumping ag­gressive or corrosive gases or vapors.
Consider interactions and chemical reactions of the pumped media. Ensure that the materials of the
pump’s wetted parts are compatible with the pumped substances, see section “Technical data”, pg. 17.
When changing the substances pumped, we recom-
mend purging the pump with air or inert gas prior to changing the pumped media. Purging the pump will pump out residues and it will reduce the possibility of reactions of the pumped substances with each other and with the pump’s materials.

Safety during operation

Adopt suitable measures to prevent the release of dan-
gerous, toxic, explosive, corrosive, noxious or pollut-
ing uids, vapors and gases. To prevent any emission
of such substances from the pump outlet, install an appropriate collecting and disposal system and take protective action for pump and environment.
You must take suitable precautions to prevent any for-
mation of explosive mixtures in the expansion cham­ber, in the oil reservoir, or at the outlet of the pump. In such circumstances, mechanically generated sparks, hot surfaces or static electricity may ignite these mix­tures. Use inert gas for gas ballast or venting, if neces­sary.
Drain appropriately or otherwise remove any poten-
tially explosive mixtures at the outlet of the pump, or dilute them to non-explosive concentrations.
page 13 of 49
Never operate this pump if it has a damaged cord or
plug.
+ If the pump is not working properly, has been dropped
or has fallen into water, contact your pump service pro­vider.
+ Prevent any part of the human body from coming into
contact with vacuum.
+ Always provide a free and pressureless exhaust out-
let. Make sure that the exhaust tubing cannot become blocked.
+ Comply with applicable regulations when disposing of
chemicals. Take into consideration that chemicals may be contaminated. Take adequate precautions to pro­tect people from the effects of dangerous substances (chemicals, oil mist, thermal decomposition products of uoroelastomers). Use appropriate protective cloth­ing and safety goggles.
+ Failure of the pump (e.g., due to power interruption),
failure of connected components or of parts of the sup­ply, or a change of parameters must not be allowed to lead to a dangerous situation under any circumstanc­es. In case of a leak in the manifold or at the shaft seal, pumped substances might be released into the environment or into the pump housing or motor.
Especially comply with notes on use and operation and
maintenance.
+ The residual leak rate of the equipment might render
possible an exchange of gas, albeit extremely slight, between the environment and the vacuum system.
Adopt suitable measures to prevent contamination of
the pumped substances or the environment.
• Ensure that no parts of your clothing, hair or ngers
can be caught or drawn in at the inlet of the pump.
Never insert ngers or drop any other object into the
page 14 of 49
inlet or outlet.
• Pumping at high inlet pressure may lead to overpres­sure at the gas ballast valve. Pumped gases or con­densate might be expelled if the valve is open. If an in­ert gas supply is connected to the gas ballast, ensure that its inlet pipeline is not contaminated.
• Check oil level of the rotary vane pump (through sight
glass) every time before starting the pump.
Pay attention to the safety symbol ”hot surfaces” on the equipment.
During operation the surface temperature of the pumps
NOTICE
may exceed 176°F (80°C). Make sure not to touch the pumps accidentally.
Hot parts may cause burns if touched. Adopt suitable
measures to prevent any danger arising from hot sur­faces or electric sparks. Ensure that hot surfaces of the pump do not cause burns. Provide a suitable con­tact guard if necessary.
• A power failure may cause accidental ventilation of the
pump or the vacuum system, if the manual gas ballast valve (RE 2.5 / RZ 2.5 / RE 6 / RZ 6 / RE 9 / RZ 9) is open. If this constitutes a potential source of danger, take appropriate safety measures, e.g., install a sole­noid operated gas ballast valve.
Prevent the backpressure of gases and the backow of
condensates at the outlet. Provide appropriate protective measures to allow for the possibility of failure and malfunction. The protective mea­sures must also allow for the requirements of the respec­tive application.
Single-phase motors are protected by a self-hold ther­mal cutout in the winding. Three-phase motors are protected by a circuit-breaker isolating all poles in case of overload.
